Porn university: Waseda student adult video star Mao Watanabe poses for nude shoot with Keio graduate Saiko Yatsuhashi

It’s the battle of the universities! Waseda versus Keio: which student is hotter?

We previously wrote about the porn debut of a Waseda University student.

That same student, Mao Watanabe (渡辺まお), has now teamed up with Saiko Yatsuhashi (八ツ橋さい子), a graduated of Keio, for a nude photo shoot that is a clever take on the traditional rivalry between the two colleges, the top private universities in Tokyo. Not only is this a full-frontal “hair nude,” it also has some serious lesbian tones.

Saiko Yatsuhashi is 27 years old and already an experienced JAV performer with multiple credits to her name.

If it’s true that Watanabe is still actually attending Waseda University (or Sodai for short), we would love to know what her fellow students and teachers think — because we are sure she can’t have kept her “part-time job” a secret from the campus. It could make for some awkward preclass corridor banter…
